This report touches upon the rough outlines of risk analysis in history, methodology and scientific. In the historical trajectory, probability theory and fuzzy set theory play key roles. Probabilistic methods successfully deal with random uncertainty in risk issues and fuzzy methods are good at the uncertainties caused by incomplete information. Divination is an ancient meaning of “risk assessment” without any scientific component. The dynamic risk analysis and the risk analysis based on internet would be most activity for recognizing the risks in the real world.
